Specification of Letters Patent.

Patented Nov. 23, 1915..

Application filed May 26, 1915. Serial No. 30,491.

To all whom t may concern Be it known that I, JAMES W. S'rm'rori, a.

citizen of the United States, and a resident of the city of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Hydrocarbondurners; and I do hereby declare that th-e fo-llowing is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention .relates to an improved type of hydro-carbon burner embracing a number of novel features of construction andoperation, and operating at high eficiency to perform the purpose for which designed.

lt is an object of this invention to construct a burner embracing an improvedl arrangement of fuel supply and generator pipes, as well as an improved type of outlet nozzle from which the fluid issues for combastion.

1t is also an object of this invention to construct a burner embodying an improved arrangement of generator pipes and air supply means to insure complete combustion of a hydro-carbon fluid with an intensely hot and clean flame, the arrangement further permitting detachment and removal of the generator supply pipe as a` whole for cleaning by simply loosening a union joint and without disturbing other parts of the device.

lt is furthermore an important object of this invention to provide a burner construction wherein an improved type of base associated with a novel arrangement of burner pipes and burner is provided, and with drip pans for generating purposes having air ducts associated therewith in a mannerfor most efficient operation in securing complete combustion.

lt is finally an object of this invention to construct a burner simple in construction, and operating efiiciently to effect complete combustion of the fuel at all degrees of regulation.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

ln the drawings: Figure 1 is a top plan view of a double burner embodying the prin# ciples of nmy invention. Fig. 2 is a section taken on line 2-2 of Fig. 1, with parts shown in elevation and with parts omitted.

Fig. is a detail section taken on line 3-3 of Fig. l. Fig. l is an end view of the burner.

As shown in the drawings: rl`he reference numeral l, indicates as a whole a metal base which is shown as rectangular in shape, though not necessarily so, and formed on the upper surface of said base are circular ribs 2, each forming in the area confined thereby a drip pan into which the oil is poured for generating pur oses. Formed on the upper surface of said ase 1, which preferably may be a casting, wlthm the area confined by said circular ribs 2, are inlet air nozzles 3, there being two formed on each of the drip pans and one disposed diametrically opposite the other.

An aperture 4, is provided in the surface of the top wall of said base l, and between the respective nozzles 3, at the center of each of the drip pans formed by the ribs 2, the metal surrounding said apertures 4, as clearly shown in Fig. 2, being formed upwardly therearound from the surface of the 30 drip pan to prevent oil poured into the drip pan from fiowing therefromthrough said apertures.

As shown in the figures, the base l, is

formed for two burners, and two generator supply pipes of U-shape are provided, the upper or generator branch thereof denoted by the reference numeral 5, and extending diametrically over the drip pan between the air nozzles 3, as clearly shown in Figs. l and 2, and the other branch 7, thereof, of each., of said pipes extending downwardly through a central opening 6, in the top wall of the base 1, and bent inwardly terminating at a point beneath the central apertures 4, of

each of the drip pans formed on said base. The branch 5, of each.of saidpipes is connected into an elbow 8, which is in turn connected to a short pipe section 9, connected into a union 10, which serves to connect said pipe section to a supply line 11, each provided with valves 12, as shown in Fig. 1, and connected to one another at a T 13, which leads to a main supply line 14.

Threaded on the end of the branch 7, of each of the generator supply pipes, is a cap 15, having an aperture 16, in the wall thereof adapted to be registered directly beneath said aperture 4, in the top wall of the base,

affording an outlet nozzle for fuel admitted to be burned through said branch pipe 5 7. Secured in any suitable manner upon the pose limiting the patent granted .otherwise inner surface of one of the side walls of the base 1, as shown in Big'. 3, is a bracket 17, aording a drip pan 18, disposed directly beneath the cap 15, so that in the event of an overflow of fluid through the nozzle 16, the same will drip downwardly and he caught in said drip pan 18, and eventually evaporated and drawn upwardly through the aperture e, or through the air inlet nozzles 3.

Attached upon the branch pipe 5, is a deector or bathe plate 19, disposed direct-ly above the drip pan, and toward which the various passages through which the duids how are directed, the liuids intermingling with one another and being deflected around the edges of said plate.'

The'operation is as follows: rlhe supply of fuel from the pipes 11, to the burners is governed by the valves 12, and in starting the burners a quantity of fuel is first poured into the drip pan formed in the upper surface of the top Wall of the basel, and the same ignited, thereby heating the branch 5, of the supply pipe. rlhe novel arrangement of air inlet nozzles 3, permits a supply of air to be directed into the jet of fiuid for conibustion issuing from the nozzle openingl i6, together With that air passing inwardly and upwardly through the aperture with the fuel to insure complete combustion of the fuel with a hot, clean flame. rlhe size of the naine is not only due to the adjustment of the valve 12, but depends to some extent upon the size of theaperture 16, in the cap 15, and it is obvious that different caps 15, may be used, having' diderent sized apertures or nozzles therethrough, whereby the maximum size of darne for fuel consumed may be pre-determined. The union 10, permits the generator supply pipe 5*-7, to be readily detached for cleaning, and the entire structure, due to the arrangement of the parts, is easily accessible at all points. The deiector or balile plate i9, serves further to intermingle the air with the fuel as the same pass upwardly through the respective passages provided therefor, to insure complete combustion thereof, and also acts to'distribute the heat to the generator pipe by preventing concentration and direct application of the flame to onepoint on the pipe.

l am aware that various details of construction may be varied through a wide range without departing 'from the principles of this invention, and l therefore do not purthan necessitated by the prior art.
